Many IT projects experience problems because the development time and/or resource
requirements are underestimated. Which of the following techniques provides the
GREATEST assistance in developing an estimate of project duration? -
ANSWER Program evaluation review technique chart
This will help determine project duration once all the activities and the work involved with
those activities are known
The use of object-oriented design and development techniques would MOST likely: -
ANSWER facilitate the ability to reuse modules.
One of the major benefits of object-oriented design and development is the ability to reuse
modules
Which of the following should be included in a feasibility study for a project to implement an
electronic data interchange process? - ANSWER The necessary communication
protocols
The communications protocols must be included because there may be significant cost
implications if new hardware and software are involved, and risk implications if the
technology is new to the organization.

,A company has implemented a new client-server enterprise resource planning (ERP) system.
Local branches transmit customer orders to a central manufacturing facility. Which of the
following would BEST ensure that the orders are processed accurately, and the
corresponding products are produced? - ANSWER Verifying production of customer
orders
Verification of the products produced will ensure that the produced products match the
orders in the order system.
Once an organization has finished the business process reengineering (BPR) of all its critical
operations, lan IS auditor would MOST likely focus on a review of: - ANSWER post-BPR
process flowcharts
An IS auditor's task is to identify and ensure that key controls have been incorporated into
the reengineered process.
When reviewing a project where quality is a major concern, an IS auditor should use the
project management triangle to explain that: - ANSWER Increases in quality can be
achieved, if resource allocation is decreased
The three primary dimensions of a project are determined by the deliverables, the allocated
resources and the delivery time. The area of the project management triangle, comprised of
these three dimensions, is fixed. Depending on the degree of freedom, changes in one
dimension might be compensated by changing either one or both remaining dimensions.
Thus, if resource allocation is decreased, an increase in quality can be achieved if a delay in
the delivery time of the project will be accepted. The area of the triangle always remains
constant.
Documentation of a business case used in an IT development project should be retained
until: - ANSWER The end of the system's life cycle
A business case can and should be used throughout the life cycle of the product. It serves as
an anchor for new (management) personnel, helps to maintain focus and provides valuable
information on estimates versus actuals. Questions such as "Why do we do that?", "What
2
, was the original intent?", and "How did we perform against the plan?" Can be answered,
and lessons for developing future business cases can be learned.
During the review of a web-based software development project, an IS auditor realizes that
coding standards are not enforced, and code reviews are rarely carried out. This will MOST
likely increase the likelihood of a successful: - ANSWER Buffer overflow
Poorly written code, especially in web-based applications, is often exploited by hackers using
buffer overflow techniques
When identifying an earlier project completion time, which is to be obtained by paying a
premium for early completion, the activities that should be selected are those: -
ANSWER That have zero slack time
A critical path's activity time is longer than that for any other path through the network. This
path is important because if everything goes as scheduled, its length gives the shortest
possible completion time for the overall project. Activities on the critical path become
candidates for crashing (i.e, for reduction in their time by payment of a premium for early
completion). Activities on the critical path have zero slack time and conversely, activities with
zero slack time are on a critical path. By successively relaxing activities on a critical loath, a
curve showing total project costs versus time can be obtained.
Which of the following should an IS auditor review to understand project progress in terms
of time, budget and deliverables for early detection of possible overruns and for projecting
estimates at completion? - ANSWER Earned value analysis
This is an industry standard method for measuring a projects progress at any given point in
time, forecasting its completion date and final cost, and analyzing variances in the schedule
and budget as the projects proceeds. It compares the planned amount of work with what
has actually been completed to determine if the cost, schedule and work accomplished are
progressing in accordance with the plan. EVA works most effectively if a well-informed work
breakdown structure exists.
